The black mass is the concentrated lithium and other metals left when lithium EV batteries are recycled into their parts. This black mass is then processed along with other raw materials to make new batteries. There are these Chicken Littles who say that EV batteries are too expensive, then contradict themselves by saying the EV

This sounds like it could revolutionize hydrogen electrolysis from water. Currently the electrolysis requires catalyst made of platinum which is rare and costly. “Graphene discovery could help generate hydrogen cheaply and sustainably.” ScienceDaily. ScienceDaily, 23 August 2023. <www.sciencedaily.com/releases/2023/08/230823122519.htm>.
Electric car batteries and all other lithium batteries are processed into ‘black mass’ at this Li-Cycle facility in Gilbert AZ. 95% of the batteries is recycled into inert, mostly plastic waste, copper and other heavy metals, and black mass where the lithium, cobalt and other valuable minerals are. The process starts with shredding the batteries

This sounds like it could be developed into a very important process. Methane + sunlight + boron nitride catalyst. The end products are hydrogen and just carbon – not CO2. So the carbon never enters the atmosphere, never becomes a greenhouse gas. Methane + Sunlight + Catalyst = Emissions-Free Hydrogen, Say UCF Researchers

New research has enabled fixating nitrogen easier than by the Haber-Bosch process. About half the world’s food supply depends on the fertilizer made by the Haber-Bosch process. It is imperative that we end the use of fossil fuels in the Haber-Bosch process because its end product is CO2 greenhouse gas. It must be replaced by

Neil deGrasse Tyson explains why the remarkable change in water at 4 degrees C is why we are alive today. When water gets colder it gets denser, until it reaches 4 degrees C, then it gets less dense as it gets colder until it freezes at 0 degrees C. This causes the ice to float

This Cleantechnica article about research and development advancements on batteries using aluminum-ion and aluminum-sulfur chemistries. German Universities; Lyten company announcing opening a pilot battery factory for lithium-sulfur cells. Quote: “”Aluminium is the most abundant metal in the Earth’s crust and its recycling is easy. Its high volumetric capacity of 8040 mA-h/cm−3 as a negative electrode

This research from Canadian Dalhousie U. and Jeff Dahn says they developed a high energy density battery that could last for 100 years. The energy density is better than LFP cells. The problem is that it requires cobalt, nickel. https://electrek.co/2022/05/24/tesla-battery-research-paper-high-energy-density-battery-last-100-years/
